Western Digital Releases ‘Gold’ HDDs for Datacenters
Samuel Wan / 3 years ago
Coloured drives have long been a mainstay of Western Digital branding. The old Blue, Black, and Greens were supplemented in recent years by the addition of the Red and Purple lineups. Today, Western Digital has released a new colour, Gold, for the datacenter. The new Gold WD HDDs will co-exist with the current WD Re lineup of enterprise drives for a while but the new family will eventually supplant the old.
The 3 drives launching today are the 8TB WD8002FRYZ, 6TB WD6002FRYZ and 4TB WD4002FYYZ. The drives are all SATA 6 Gbps 3.5″ form factor with 7200rpm spindle speed, an extra large 128MB cache and using good old PMR platters. The 8TB model uses the HelioSeal helium fill that HGST, a WD subsidiary, pioneered with their drives. With lower capacities, the 6TB and 4TB are regular drives but the 6TB model does feature a ‘media cache’ to speed up writes. This sounds a lot like a NAND cache, making the 6TB Gold the first enterprise hybrid drive.
Due to the use of helium, it’s interesting to see the 8TB drive actually has lower power consumption than the other too. On the other hand, the NAND cache makes the 6TB the best performing model. The 4TB is also somehow 18% faster than its Re predecessor. The 4TB and 6TB also feature their own form of HGST involvement as well, being made by HGST Japan. Perhaps this is a sign that Western Digital is moving their enterprise business over to their HGST division.
